Clamping voltage, also referred to as let through voltage or the Voltage Protection Rating (VPR), is the amount of voltage a surge protector permits to pass through it to the attached load (ex: a TV) during a surge event.

How do you determine correct size varistor on a 24vac coil?
is this coil a single shot solenoid or is it used as a filter i assume you want to know a good value for a varistor to stop voltage spikes from the reverse EMF which is aprox. 4X the input voltage. so i would say to use 2X-3X the input Voltage so 48 or 72 Volt MOV (Metal oxide varistor) You want the varistor to be several volts greater than the peak voltage of the signal across which it is connected. 24 volts is probably the RMS value of the coils voltage. Your varistor must be selected to be greater than the peak voltage. When the voltage exceeds the clamping voltage of the varistor, it conducts current, preventing the voltage from reaching a dangerous level. If the elevated voltage is maintained for too long a time, the varistor will heat to a point where the metals in it melt and fuse together, causing a short. This also poses the posibility of a fire risk, as the current is now conducting heavily through the varistor. This is what often happens to a varistor in a power strip when lightening strikes nearby. It renders the power strip useless. But the connected devices are usually spared.
What is the use of metal oxide varistor disc in Lightning arrestor?
I think your answer is given in previous question -( correct size of varistor across 24v coil) I am just pasting the same here. . . "When the voltage exceeds the clamping voltage of the varistor, it conducts current, preventing the voltage from reaching a dangerous level. If the elevated voltage is maintained for too long a time, the varistor will heat to a point where the metals in it melt and fuse together, causing a short.

How does ZnO varistor work?
A varistor is essentially a transient voltage suppressor or a surge protector. They are used in a number of devices that need a consistent voltage across the system for reliable operation. In the power industry, varistors are used in high voltage transmission systems to protect the grid from line surges caused by things like lightning strikes. Varistors are variable resistors that act as a shunt, allowing the flow of current under normal voltage but restricting current flow at or above the clamping voltage-the voltage required to trigger the sintering of the varistors zinc oxide and ceramic matrix. Varistors are vital in all electrical transmission applications, but new and better varistors are needed to protect extremely high voltage systems from line surges. Varistor technology is one of the limiting agents on the maximum voltage of high voltage transmission systems. Using zinc-oxide nanoparticles in the varistor matrix will produce varistors with better performance characteristics, ultimately increasing reliability, more efficient transmission technologies and smaller vasristors. This technology will aid in the development of super high voltage transmission networks that operate at voltages as high as 1500kV while still maintaining grid stability.

What does the initials MOV stand for?
The initials or acronym MOV may stand for many things. It can mean margin of victory, manually operated valve, or multiple organ failure.
When choosing a mov?
If you are asking about MOV as in a Metal Oxide Varistor, then you choose the value at the point of clamping. If your circuit is built for 120v, but you obviously derated your components, so they should survive to around AT LEAST 150v. So you would choose a 150v MOV. The MOV is a path to GROUND. In normal operation, the MOV does NOTHING! It is a closed valve (or OPEN circuit) When the voltage on the line reaches the MOV's rated voltage, 150v in this case, the valve opens (circuit closes) and gives the spike a path to ground, instead of through your circuit. Here is a link to surge suppression in general and includes MOV's: http://www.naturalhandyman.com/iip/infelectrical/infsurgeprotect.html
Is CaO a metal oxide or non metal oxide?
Calcium is a metal, therefore this is a metal oxide.
Is phosphoros a metal oxide or a non metal oxide?
Phosphorus is not an oxide. It is an element. It is a nonmetal.
When oxygen is bonded to a metal it forms?
The oxidation of a metal produces a metal oxide. For example, calcium + oxide -> calcium oxide
